  1. 1. Geometallurgical approach to understand how the variability in mineralogy at Zinkgruvan orebodies affects the need for copper activation in the bulk rougher-scavenger flotation

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ivan Belo Fernandes; [2017]
    Keywords : Geometallurgy; Zinkgruvan; Zn-Pb flotation; ore variability; mineral chemistry; pyrrhotite; magnetic separation;

    Abstract : Zinkgruvan is a Pb-Zn-Ag deposit located in south-central Sweden, owned and operated by Lundin Mining. The ore is beneficiated by a collective-selective flotation circuit, recovering both galena and sphalerite in a bulk rougher-scavenger flotation stage and later on separating them into two final products.

  2. 2. Softening Efficacy of Various Solvents on Gutta-percha and Root Canal Sealer

    University essay from Umeå universitet/Institutionen för odontologi; Umeå universitet/Tandläkarutbildning

    Author : Andreas Boman; Jakob Selvin; [2016]
    Keywords : Endodontic treatment; endodontic retreatment; gutta-percha solvent; chloroform endodontic; sealer antimicrobial;

    Abstract : Solvents have been used in endodontic retreatment for a long time and the dissolving effect is well proven. Latterly chloroform has come in a bad light due to its possible carcinogenicity. Despite the negative health effect it is still used in dental environment. READ MORE

  3. 3. Measurement and Comparison of Volumetric Shrinkage of Various Sealers Registered by a Video Imaging Technique Device

    University essay from Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Author : Hossein Sobhani; Shahab Rezai; [2016]
    Keywords : Sealer; AcuVol;

    Abstract : Obturation ability of root canal treatment materials are one of the factors that affect the prognosis of root canal treatment with essence of complete closure of the root canal. Cold lateral condensation is one of the most common techniques used for endodontic therapy which sealer acts as sealing and bonding agent between dentin and gutta-percha. READ MORE

  4. 4. Simulation of Metal and Metal Oxide Nanoparticle Sedimentation in Solution Using a Computational Model

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Sara Isaksson; [2016]
    Keywords : Nanoparticles; sedimentation; simulation; fractal dimension; aqueous environment; Nanopartiklar; sedimentering; simulering; fraktaldimension; vattenmiljö;

    Abstract : Nanoparticles are used in many different applications because of their small size and unique properties. The usage is increasing rapidly, which will increase the nanoparticle exposure to the environment. READ MORE

  5. 5. Light induced textile substrate with switchable and reversible wettability : Development of a switchability and reversibility effect between hydrophobic and hydrophilic states on a polyamide-66 textile substrate

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Rosalinda Sardo Infirri; [2016]
    Keywords : Polyamide-66; Titanium dioxide; Silicone; Zinc oxide; Azobenzene; Switchability; Reversibility; Hydrophobic; Hydrophilic;

    Abstract : Biomimicry means literally ‘imitation of life’ and is providing sustainable solutions for challenges that are occurring in the human lives. To date, the biomimic research reports that wettability in nature, e.g. READ MORE
